Giant Earthquakes Will Continue

You would think this would be huge news in America. California or Alaska, at least. Mainland Alaska hasn't had a huge 9+ earthquake since before the Alaskan Pipeline was built but you can bet, it has a very good chance of happening now. Failure of this pipeline will have catastrophic effects on our entire economy.

Then there is California. They haven't had a 9+ earthquake in over a century. Such a beast would pretty much destroy nearly everything in its path.

So here it is:

THE Indonesian earthquake behind the Boxing Day tsunami that killed 300,000 people could be the first of a series of giant quakes that will rock the world in the next 10 to 15 years, scientists have warned.

The Mediterranean is among areas at high risk, particularly the coasts of Greece and Turkey, both popular tourist destinations. The scientists are urging the installation of a tsunami warning system there as a matter of urgency.
They found that quakes such as the one in Indonesia can destabilise the whole of the earth's crust, so that one is followed by others, often thousands of kilometres away, within a few years.

"The four biggest earthquakes of the 20th century all happened within 12 years of each other, a pattern we see repeated with other quakes over many decades," said Vladimir Kossobokov of the International Institute of Earthquake Prediction in Moscow.


My own take on this: Not only do earthquakes travel in groups, so do volcanic eruptions. Roughly on a twenty year/seventy year cycle. Like the sun, it is periodic and it is because of the earth's crust flexing in unison. Energy for this builds up until released. The moon is the forgotten force here. It warps our oceans so much we have this thing called "tides" and in full moon phases, the tides are much greater than other times. The moon moves closer and then further. The relative position of the earth and sun varies too. This causes the planetary surface to flex and warp. On top of this are forces on earth itself. When vast sheets of ice form or melt, this affects the shape of the crust. Changes in the status quo leads to increases in energy released or locked up.

Right now, the Australian plate seems to have accelerated its movement as mass leaves the Antarctic plate. This shoves other plates together. Thus the earthquakes. After this, the volcanoes which are already pretty active, will increase activity. This is a far greater danger than mere earthquakes. Volcanoes alter the weather in very drastic ways.

So why isn't this news here in America? Aside from Indonesia, we are the most likely place for earth girdling catastrophic events like Yellowstone blowing up.
